Web5) The gravitational force between two objects that are 2.1x10‐1 m apart is 3.2x10‐6 N. If the mass of one object is 55 kg what is the mass of the other object? 6) If two objects, each with a mass of 2.0x102 kg, produce a gravitational force between them of 3.7x10‐6 N. What is the distance between them? WebSep 18, 2024 · Solution: In all inclined plane problems, first of all, choose a suitable coordinate system. It is common to choose the positive direction along and down the plane so that the up direction is perpendicular to the plane. Two forces always act on an object resting on a smooth inclined plane (without friction). contoh rpp ppkn kelas 8
